ABSTRACT:
A solar heat storage system is provided for greenhouses by providing the greenhouse with a gravel storage bed at the floor level, through which heated air from an air duct at the upper ridge of the greenhouse is circulated to take advantage of and store heat energy collected from the sun in the winter time. In the summer time the same system operates to maintain an even and relatively cool atmosphere within the greenhouse by disconnecting the air duct at the top, introducing fresh air from the outside and passing such air through humidifying means, thence through the gravel storage bed and out vents at the upper ridge of the greenhouse.
